shines a beam of light through the pupil onto the retina at the back of the eye

lights up the the transparent centre and back of the eye with a fine beam of light directed to the pupil

measures the pressure build-up in the eyeball

it magnifies up to 50 times and is combined with a lamp that provides a narrow beam of light through a tiny slit

to magnify = vergrößern

to provide = ermöglicht, sorgt dafür

narrow = schmal

slit = Spalt

if the eye is shorter tha usual or the lens isn't powerful enough to refract the light into the fovea; corrected by lenses, so the light refracts stronger

if the eye is longer than usual, it can be corrected by contactlenses; hard or soft so the light refracts weaker

to assess sth

it's the direction pf power. It is messured in degrees from 0 to 180 degrees.

specifies the amount of lens power of asifmatism. It is power in a certain direction.

certain = bestimmter (Richtung)

specifies the amount of lens power for near- or shortsightness. No sphere is noted as plano. If the power is a minus, it is a nearsighted presciptio. If it is a plus, it is farsighted. Mild presciptions are in the range pf plus or minus 1 to 3, high over 5 to 7.

specifies the added magnification on the lower part of multifocal lenses for near vision.

is a special power to compensate for eye alignment problems, e.g. disorders such as squints.

alignment = Ausrichtung

squints = Schielen

indicates the direction of the prism power

up, down, in, out

the power of lens in dioptre is nummerally equal to 1 m divided by the focal length in metres.

More simply, dioptre is the reciprocal of the focal length in metres.
